Abstract

We have investigated the differences in (magneto-)resistance, magnetism and morphology of thin films of La_0.73Ca_0.27MnO₃, grown by sputter deposition in high oxygen pressure on substrates of either SrTiO₃ or LaAlO₃. We find that growth on SrTiO₃ is epitaxial and sooth, in contrast to growth on LaAlO₃, where islands are formed at low coverage, leading to rough and disordered films at higher coverage. This type of deposition appears to lead to different film morphology than films grown by laser ablation.
